TO ALL WHOM IT MAY CQNCERN: l

Beit known that I, HIRAM TYLER, of Gaines, inthe county of Orleans, and in the State of New York, have `invented certain new and useful Improvements in Pumps; and do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. Y Y

,In the annexed drawings, making'part of this specification, Arepresents a cylinder, and B and C' represent two pipes which are placed one upon each side ofdt. D and E represent two cast metallic boxes, each having three annular openings to receive the ends of the cylinder, and the ends ofthe two pipes B and C; E being' the bottom box, the lower end of cylinder AI is placed upon it in its centre openings, and the bottoms of the pipes B and C are placedp'iu theopenings upon each side of it, as seen. The upper box Dis placed so as to cover the upper ends of the cylinder and pipes, and rods J J being passed through ears formed on thefour sides of these boxes, and nuts being passed over'the ends of these rods, the two boxes are clamped tight against theV cylinder and pipes C and B. n Each of the boxes has a partition, K, cast crosswise of -it, dividing the centre opening, for the Vend of the cylinder, in two parts; W representing, in4 iig. 4, the opening which is divided. The chambers upon each side of partition K connect with the openings T and T, which receive the ends of the pipes. The openings in these boxes, which receive the ends of the cylinder and `pipes, are formed with seats, upon which packing may be placed ltc make a close joint. Upon the seat S of opening W I first place a valve-plate, L, and upon 4this plate I place the packing-ring. The plates L rest not only upon the seat S, but also upon the partition K, and said plates are provided with perfor-ations upon each side of the partition, and these perforations are covered with flap-valves g d min. Upon each of these plates the valves are so arranged that one opens upward and the other downward. F represents a piston-rod,which isprovided, upon its lower end, with a piston-head', constructed as follows:l I use Aan annular ring, made of metal, which is fitted loosely within the cylinder. This ring is bevelled inward from each edge of its periphery, so that it is V-sbaped on its inside, as represented. H represent two leather plates or disks, which are made larger in diameter than the diameter of the cylinder. These disks are placed upon each side of the ring, and two metallic cups I I arev placed, with bottoms inward, against the disks H. e e represent nuts, which tit over the thread upon Vthe lower end of the piston-rod, and serve to bind the-cups tightly against the disks H, and the ring Gbinding the several parts v together, and the 'head thus formed to the piston-rod. The piston-rod may be packed in Vany of the known andl usual ways where it enters the cylinder.

lIn using this pump I attach Ya pipe at the orifice?, which passes down to the water of the well. Avpipe passes up from orifice O, to the top of the well, to deliver the water. It will be secn that after the piston-head has been pushed down to the bottom of the cylinder, so as exclude the air as it is being drawn up, the valve h i rises, and the water, passing up through oriiiceP in the lower box, lls the cylinder beneath the cylinder-head as fast as said head rises. When the piston-head descends, water passes up pipe B, and through valve m, into the cylinder, following the head down and filling the cylinder above the head. As the piston-head begins to descend the valve g opens, andthe water from beneath the head is forced up pipe C and out through orifice O.

When theohea'd ascends again the'water is received in below it, as has been described, through valve h, and the water above it is forced outthrough valve wand into or through orifice O. Thus at each down stroke water is received into the cylinder above the head, and discharged from it below the head, while at each upward stroke the reverse is the case, the water being received below and discharged above. I may submerg'e this pump, closing the port or orice P, and perforating the side of pipe` B, or `making an opening to it through the upper box to allow the water to enter. A strainer can be used for excluding any impurity in the water. i

Having thusfully described my invention, what I claim as new, and desire to secure by LcttersIatent, is The boxes D and E, pipes B4 C, valve-plates L, and 'piston-head as constructed with its piston-rod F, the

several parts being used with the cylinder A, when combined,larr'anged`, and operating in the manner substan-` tially as and for the purposes herein specified. A

In testimony that I claim the foregpin'g I have hereunto set my hand this 20th day of June, 18767.
